Well, this is where the fountains are and, one would imagine, the children's playground is there too. Although, since I've started paying more attention to exactly where scenes are being filmed, I've noticed that Jackie Chan is prone to filming all over the place and sticking it together. Still, as the park is home to one of my all time favourite fight sequences, I shall make a homage there next month and see if the playground is there.
There's no Street View inside the park, but this Panoramio image (thanks to KaySin) is looking across the pond, at the spot where Maggie Cheung is sitting.
